Embodiment

[0071] Client sends encrypted data test:

[0072] Such as Figure 7 As shown, we captured several sets of data continuously uploaded by the acquisition terminal to the cloud server. The 13 sets of raw data we uploaded are (9,3)(18,9)(8,10)(13,5)(19,14 )(7,13)(11,13)(4,7)(6,4)(12,7)(4,6)(2,5)(16,3), analyze the data packet and find the data It is completely encrypted, and the original data cannot be obtained.

[0073] Cloud server storage ciphertext data test:

[0074] Upload a set of medical data directly from the txt file, then print out the data received by the cloud server in the cloud database, and observe the changes in the data, such as Figure 8 is the data before upload, Figure 9 The data connected and stored for the cloud server can be seen through comparison that all user data is encrypted and stored in the cloud server, and the cloud server has no knowledge of the data content.

Abstract

The invention discloses a secure transmission method of private cloud medical data. The method comprises the following steps: encrypting collected data by calling an IP core of an SM4 algorithm by an ARM through an AXI bus, performing digital signature on the encrypted data by the ARM by using an SM2 algorithm after the data are encrypted, calling the IP core of an SM3 algorithm to perform operation acceleration in the signature process, and sending the data to the cloud by using WIFI. By adoption of the secure transmission method disclosed by the invention, the following problem is solved: before the existing personal private cloud medical data need to be encrypted to ensure the security before being sent to a cloud server, however the data bandwidth required for high-precision medical data is very large, and the computing ability of the traditional software cannot satisfy the real-time encryption demand, the security of the data is guaranteed by the SM4 algorithm in the secure transmission method disclosed by the invention, the reliability of the data is guaranteed by the SM2 digital signature algorithm, and the privacy protection of the personal medical data in the transmission process is accomplished efficiently in real time by means of the parallel processing ability of hardware.

Description

technical field [0001] The invention belongs to the technical field of information security, and relates to a method for securely transmitting private cloud medical data. Background technique [0002] In recent years, with the integration of medical sensor technology, mobile communication technology (3G, LTE, 4G, etc.), cloud computing and related wireless communication technology and network technology, the Wireless Mobile Healthcare Monitoring Network based on WBAN , WMHMN) has been in-depth development. Compared with the traditional medical system for treatment after the onset of illness, by virtue of cloud computing and mobile medical technology, WMHMN can free patients from time and place restrictions, and monitor physical condition information in real time without affecting daily life, realizing common Early monitoring and prevention of diseases, postoperative auxiliary medical rehabilitation and emergency treatment have reduced medical costs and relieved the pressure...
